C) How prominent is diabetes following Whipple procedure? Being healthy and active, major post-operative issues or changes to worry about?

My non-fasting glucose was pretty high at the time of my initial PDAC diagnosis. Pancreas was obviously not functioning properly... was given some counseling, insulin, and a Dexcom.

Post-Whipple, definitely diabetic. Decent control if I exercise and watch what I eat, but can't avoid some sugar spikes w/o insulin.

PEI (Pancreatic Enzyme Insufficiency) is another outcome of having your pancreas chopped in half. You may need enzyme replacement (e.g., Creon) to digest food properly after a Whipple.
